Waterborne functionalization of cellulose nanofibrils with norbornenes and subsequent thiol-norbornene gelation to create robust hydrogels

Ultrasonic interfacial crosslinking of TiO2-based nanocomposite hydrogels through thiol–norbornene reactions for sonodynamic antibacterial treatment

“…This phenomenon could be attributed to the ester bond hydrolysis between carbic anhydride and dextran backbone due to the enzyme in the cell culture media. 103…”

“…This phenomenon could be attributed to the ester bond hydrolysis between carbic anhydride and dextran backbone due to the enzyme in the cell culture media. 103 The cytocompatibility of the TiO 2 @MS-SH/Nor-Dex NC hydrogels was further investigated using mouse embryo fibroblasts (MEFs) along with live/dead cell staining and alamarBlue assay. The extract solutions used for cell culture were prepared by soaking the hydrogels in the serum-containing media for 24 h. The live/dead staining images showed that MEFs could keep proliferating for up to 5 days (Fig.…”

Hierarchical Design of Tissue‐Mimetic Fibrillar Hydrogel Scaffolds

“…[ 96 ] CNFs can be surface functionalized, for instance, with norbornene groups and then crosslinked through UV‐ or thermally‐initiated thiol‐ene click reactions to create robust fibrillar hydrogels. [ 97 ] The fabrication of fibrillar hydrogels based on the entanglement and bundling of CNFs has been recently reviewed. [ 98 ] However, CNFs have been more widely explored as reinforcement elements in combination with different polymer matrices than as building blocks to form hydrogels by themselves.…”
